Cold air continued to pour into the East, while rain showers spread across the Great Lakes and Northeast on Wednesday. A low pressure system spinning in eastern Canada continued to push a cold front eastward. This system moved from the Great Lakes, up the Ohio River Valley, and into the Northeast, and triggered scattered rain showers throughout the day. This system also brought cooler temperatures to the region, with overnight lows in the 30s and daytime highs in the 50s. The tail end of the cold front extended into the Tennessee Valley and Lower Mississippi River, but rainfall has not yet developed in these areas.

Behind this system, a trough of low pressure moved into the Northern Plains from Canada and produced a combination of snow and rain showers. Cold air continued to pour into these areas, with overnight lows dropping into the upper teens across the Northern High Plains. Daytime highs only reached into the 30s and 40s across the Dakotas and parts of Minnesota. Out West, a low pressure system off the coast of California advanced eastward and pushed some moisture onshore. This kicked up scattered showers across parts of central and southern California, and increased chances of thunderstorms across the Desert Southwest. Rainfall totals remained less than a tenth of an inch across the region.
